Do you need a PSR?

Tick anything that applies to your new or modified equipment.

Start by ticking a box

Section 7 of Regulation 851 lists the circumstances that trigger a review in an Ontario factory. Most plants trip at least one without realising it.

Indicative only. A formal trigger determination is made by the reviewing professional engineer against the full Table to section 7 — and we do that at no charge.

What we do

Six practice areas, one engineering file. If a piece of equipment needs a seal before it runs, it falls somewhere on this list.

Pre-Start Health & Safety Reviews

The full PSR: trigger determination, site inspection, standards gap analysis, sealed report and a plain-language deficiency list your team can actually close out.

  • New installs, relocations and modifications
  • Retroactive reviews on legacy equipment
  • Re-inspection and sign-off after corrections
O. REG. 851, S. 7

Machine safeguarding

Risk assessment and guard design for presses, conveyors, robots, CNC and custom builds. We specify the protective measure, then verify it performs to the required level.

  • Task-based hazard identification
  • Performance level and safety distance calculations
  • Guard, interlock and control system specification
CSA Z432 · ISO 13849 · CSA Z460

Dust hazard analysis

Combustible dust is the hazard most Ontario plants underestimate. We characterise the material, map the flame and explosion hazards, and give you a ranked mitigation plan.

  • Material testing coordination (Kst, Pmax, MEC, MIE)
  • Compartment-by-compartment DHA
  • Housekeeping and ignition-control programs
NFPA 652 · 654 · 664 · 61

Explosion protection & dust collectors

Collector siting, venting, isolation and suppression reviewed against the standard — plus the documentation your insurer keeps asking for.

  • Deflagration venting and vent path calculations
  • Isolation, ducting and return-air review
  • Existing collector compliance upgrades
NFPA 68 · 69 · 654

Commissioning witnessing

Independent Cx attendance and functional testing witnessing, so the record of what actually happened on site is written by an engineer, not the installer.

  • Functional and integrated systems testing
  • Witnessed start-up and performance verification
  • Issues logs, hold points and closeout reporting
INDEPENDENT THIRD PARTY

TAB & anchor testing

Testing, adjusting and balancing verification on ventilation and dust systems, plus field load testing on anchorage for racking, guarding and equipment.

  • Airflow, capture velocity and duct balancing verification
  • Anchor proof-load testing and reporting
  • Post-remediation re-testing

Build your scope

Four questions to size the job. You get an indicative timeline and a list of exactly what to send us — then it drops straight into the request form.

Indicative scope

Time on siteHalf a day
Sealed report5–7 business days
Commercial basisPer apparatus
Send usMachine manual, layout drawing, photos of the guarding

Indicative only — a firm fixed fee follows the free scope call. Rush turnarounds are available when a start-up date is at risk.

Standards we work to

Search the codes and standards behind our findings. If you've been handed a clause number and don't know what it means, start here.

How a review runs

Five stages, fixed fee, and you know where you stand before we leave the building.

Scope call

Twenty minutes on the phone with drawings or photos. We confirm which triggers apply and quote a fixed fee.

Document review

Manuals, electrical schematics, control system architecture and prior reports go through desk review before anyone travels.

Site inspection

Measurements, control verification and hands-on testing with your operators and maintenance lead present.

Sealed report

Findings referenced to the clause, ranked by risk, each with a specific corrective measure — not a vague recommendation.

Close-out

We re-verify the corrections and issue the compliance confirmation your file needs before the equipment runs.

Why plants call us back

We started SGE because too many reviews arrive as a PDF full of clause numbers and no way forward. A report you can't act on isn't engineering.

Verbal findings before we leave

You hear the critical items on site the same day, so remediation starts while the contractor is still on the floor.

Reports written for the floor

Every finding names the clause, the risk, the specific fix and who typically owns it. Your JHSC can read it without an engineering degree.

Province-wide, genuinely

Based in Eastern Ontario, on site anywhere from Ottawa to Windsor. Rural plants get the same turnaround as the 401 corridor.

Fixed fees, no scope creep

Quoted per apparatus or per line before we mobilise. If the scope changes on site, you approve it before it's billed.

Principals do the work

The engineer who quotes your project is the engineer on your floor and the engineer whose seal goes on the report.

Built for production schedules

Shutdown windows, weekend installs and night commissioning. We work when the line is down, because that's when it matters.

Sectors we work in

Twelve years of files across Ontario's industrial base.

Who signs your report

SGE is a two-principal firm on purpose. You get senior engineers on site, not a junior with a checklist.

Mahmoud runs SGE's field program — scheduling, site execution and the discipline that keeps reports moving from inspection to seal. His background spans machine safeguarding, industrial ventilation and multi-site compliance programs for manufacturers across Ontario, with a project management practice built on shutdown windows that don't move.

Carson leads the technical practice: risk assessment methodology, dust hazard analysis, explosion protection and the standards interpretation behind every finding SGE issues. His work bridges process safety and building systems, which is why SGE handles ventilation, commissioning and TAB verification as engineering — not as an afterthought.

Questions we get weekly

Who is legally allowed to perform a PSR in Ontario?
A Professional Engineer licensed in Ontario, working under a firm holding a Certificate of Authorization from PEO. The engineer must have expert knowledge relevant to the specific hazard being reviewed — a structural P.Eng is not automatically qualified to review a light-curtain installation. Ask any firm you're considering to name the engineer who will seal your report before you sign.
We've been running this machine for years. Do we still need a review?
Possibly. The obligation attaches when equipment is newly installed, relocated, or modified in a way that affects a listed circumstance — including guarding that was removed and never reinstated, or a control system that was rebuilt. Legacy equipment that has quietly been modified is the single most common finding we make on a first visit.
How long does a review take?
A single apparatus is typically a half-day on site with a sealed report inside five to seven business days. A full production line or a multi-collector dust system runs longer. Rush turnarounds are available when a start-up date is at risk — tell us the date on the scope call and we'll tell you honestly whether we can hold it.
What happens if the review finds deficiencies?
That's the normal outcome, and it isn't a failure. The report ranks each deficiency by risk with a specific corrective measure. You complete the corrections, we re-verify, and the compliance confirmation is issued. The equipment cannot be operated with workers exposed to the unmitigated hazard until that's resolved.
Do you handle the corrections as well as the review?
We specify them and we can produce the guard and interlock designs. We deliberately don't sell you the hardware or install it — an independent review loses its value the moment the reviewer has a stake in what gets bought.
Do you do combustible dust work outside of a PSR?
Yes. Dust hazard analyses are frequently commissioned on their own, driven by insurance requirements or an incident at a comparable facility. NFPA 652 expects a DHA for any facility handling combustible particulate solids, whether or not a PSR trigger exists.
What does a review cost?
It depends on the number of apparatus, the hazard type and travel. We quote a fixed fee before mobilising, on one of three bases: per apparatus, per line or cell, or a program retainer for multi-site manufacturers. The trigger determination itself — working out whether you need a review at all — is free.

Request a review

Send the equipment details and we'll come back with a scope and a fixed fee — usually the same business day. If a start-up date is at risk, call instead.
